is this a nested json?

request format: GET /trading-pairs :

[
  {
    "name": "ETH-KRW",
    "baseAsset": "ETH",
    "quoteAsset": "KRW"
  }, {
    "name": "BTC-KRW",
    "baseAsset": "BTC",
    "quoteAsset": "KRW"
  }, {
    "name": "BCH-KRW",
    "baseAsset": "BCH",
    "quoteAsset": "KRW"
  }
]

and then :

request format : GET /trading-pairs/{name}/ticker :

{
  "price": 10194500,
  "ask": 10195000,
  "bid": 10184500,
  "volume": 1752.05558316,
  "time": "2018-03-14T03:50:41.184Z"
}

I have been trying to parse json data in this format but result is unsuccessful so far how would it possible to parse data in such format?

Coders, devs, lets parse this json format.. . :)

           ===============What I Tried=============

1. Response Models:

   import Foundation
   // MARK: - TradingPair
   @objcMembers class TradingPair: NSObject, Codable {
   var id: Int
   var name, baseAsset: String
   var quoteAsset: String
   
   //var pairs: TickerByPairs?
   
   init(id: Int, name: String, baseAsset: String, quoteAsset: String) {
       self.id = id
       self.name = name
       self.baseAsset = baseAsset
       self.quoteAsset = quoteAsset
   }
   }

   ---

   
   import Foundation

// MARK: - TickerByPairs @objcMembers class TickerByPairs: NSObject, Codable { var price, ask: Float var askVolume: Double var bid: Float var bidVolume, volume: Double var time: String

init(price: Float, ask: Float, askVolume: Double, bid: Float, bidVolume: Double, volume: Double, time: String) {
    self.price = price
    self.ask = ask
    self.askVolume = askVolume
    self.bid = bid
    self.bidVolume = bidVolume
    self.volume = volume
    self.time = time
}

}

 2. API request func s:

import Foundation import Alamofire import SwiftyJSON import PromiseKit import JSONDecoder_Keypath

class ServerCommunicator {

// using this: `static  var tradingPairs: String {
    return serverEndPoint + "/trading-pairs"`
}
static func getTradingPairs() -> Promise<[TradingPair]> {
    return Promise { seal in
        AF.request(API.tradingPairs, method: .get).validate().responseData { (data) in
            guard let data = data.value else {
                let err: Error =  Error.self as! Error
                seal.reject(err)
                return
            }
            guard let tradingPairs = try? JSONDecoder().decode([TradingPair].self, from: data) else {
                let err: Error = Error.self as! Error
                seal.reject(err)
                return
            }
            //dump(tradingPairs)
            dump(tradingPairs)
            seal.fulfill(tradingPairs)
        }
    }
}

// using this: static func getPairByTicker(pairName: String) -> String { return tradingPairs + "/\(pairName)" + "/ticker" } static func getPairByTicker(pairName: String = "") -> Promise<TickerByPairs> { let decoder = JSONDecoder() return Promise { seal in AF.request(API.getPairByTicker(pairName: pairName), method: .get).responseDecodable(of: TickerByPairs.self, decoder: decoder) { response in // dump(response.value) switch response.result { case .success(let suc): return seal.fulfill(suc) case .failure(let err): return seal.reject(err) } } } } }

 3. ViewController class: 

import UIKit import Alamofire

class ViewController: UIViewController { @IBOutlet weak var tableView: UITableView! var tradingPair: [TradingPair]? var tickerByPair:[TickerByPairs]?

override func viewDidLoad() {
    super.viewDidLoad()
    getTradingPairs()
}
func refresh(data: [TradingPair]) {
    self.tradingPair = data
    self.tableView.reloadData()
}

func getTradingPairs() {
    print("api call")
    ServerCommunicator.getTradingPairs().done{ response_1 -> Void in
        print(response_1)
        for keypathValue in response_1 {
            ServerCommunicator.getPairByTicker(pairName: keypathValue.name).done{ response_2 -> Void in
                print(response_2)
            }.catch{(err) in
                print(err)
            }
        }
    }.catch{(err) in
        print(err)
    }
}

} extension ViewController: UITableViewDataSource { func numberOfSections(in tableView: UITableView) -> Int { return 1 } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { guard let data = self.tradingPair else { print("data is empty") return 0 } return data.count

}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "TradingPairCell") as! TradingPairCell
    guard let data = self.tradingPair else {
        print("again empty")
        return cell
    }

    let price = self.tickerByPair![indexPath.row].price
    let volume = self.tickerByPair![indexPath.row].volume

    cell.price.text = String(describing: price)
    cell.volume.text = String(describing: volume)

    cell.configure(data: data[indexPath.row])
    return cell
}

}

extension ViewController: UITableViewDelegate { func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat { return 44 } }

 1. Cell Class

class TradingPairCell: UITableViewCell { @IBOutlet weak var name: UILabel! @IBOutlet weak var price: UILabel! @IBOutlet weak var volume: UILabel! //var pairByTicker: PairByTicker?

func configure(data: TradingPair) {

    self.name.text = data.name

// self.price.text = data.baseAsset // self.volume.text = data.quoteAsset } }

 II. This is what i get in console:

api call data is empty data is empty
